IMPROVEMENTV IN HARVESTERS. i

Specification forming part of Letters Patent N0. 80,12*24,` dated J uly' 21, 1868.

To all whom it may concern:

Be it known that I, OLPHA BONNEY, Jr., of San Francisco, in the State of California, have invented a certain new and Improved Harvest- Helper 5 and I do hereby declare that the foli lowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters and marks thereon, which said drawings form part of this specification, and show a helper constructed uuder my invention- Figure l being a side view of such helper; Fig. 2 being a view, by transverse section, of the header-beam and spring; and Fig. 3 being a view of a modification.

In each of these figures, where like parts are shown, like marks and letters are used to indicate the parts. l

In many sections of the country where wheat c is grown to a great extent heavy rains and `winds force-it down on or toward the ground L to so great a degree that the grain cannot be cut by either a header or a low-cuttin g reaper.

` i Efforts have been made to relieve the grain from this prostrate condition by using grainlifters. These are usually constructed of springs, and have not been found eicient. The grain, when down, forms quite astrong i net-work, and the springs become entangled therein, and are frequently broken. Now, my

` f invention has for its objectelevating thegrainf stalks, and putting them in a good position for the knives of the header or harvester.

rIhis helper is somewhat of a triangular form,

` composed in part of wood a and part of metal. y. A metal strip, b, shows the lower front part, while another strip, c, covers the upper surface.

Other strips or ribs, d, are attached to the sides. The header-beam e is pivoted to the bar f at i g, and its" front end plays within the yoke h.

Between'the curve or bend of the yoke and the edge of the beam is a rubber spring, z', in

a recess, and which, beingthus sheltered, will notbeinteriered with by net-work of the grainy stalks.4

A wheel,j, is pivoted at the end of the bar` k and the sides of the box I. VThe bar k, at itsA upper end, is adjustable in the` plate m. By these means the helper can berun on a line parallel with the ground, or can be elevated i h from six to ten degrees. From four to eight of these helpers may be used with the header, the relation of them 'with the knives of the header'being indicated by Fig. 1 of the drawings, where thedotted lines 'n indicatethe y knives.

In use, the grain-stalks will be raised by the upper edge c and by the strips or ribs d, as the stalks come in contact with` these surfaces on the forward movement of the machine, and

the stalks or uncut grain in the iield will thus` be so placed before the cutters of the header or harvester as to acted upon.

The modification shown byrig. 3 is thatof a helper constructed, with the exception ofthe supporting-beam, wholly of metal corrugated .sides and ribbed top, the rim of `this being by section. y

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A helper of4 substantially `a triangular form, lhaving the upper inclined edgec and ribs d, for elevating the grain or stalks, as

herein recited. 1

2. The wheel j, adjustable bark, and box l, for the purpose set forth.
